It's quite near from the MRT Lumphini station. and it wasn't that hard to find this guest house. 7/11 was so near, so i even went there around 1 am to buy sth. The air conditionner was like a heaven. Also the hot water worked well (plus, the refrigerator was good). There were no bugs at all, i really liked it. it was really really good but soundproof wasn't that good. We could hear people talking outside (it was rare though), going up and down. But it didn't bother us that much. I am really willing to use that room again when i travel bangkok! The host was so kind really lol thank you a lot, i asked him really a lot even before our trip, but he answered all...!! I highly recommend this room to travelers.
